PORTABLE DERRICK.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed November 14, 1903. Serial No. 181,204.

T all whom it may concern:

Be it known that we, THOMAS SPENoER MILLER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, and Josnrn H. DICK- INSON, a citizen of the United States, and a resident of Montclair, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Portable Derricks, of which the following is a specification.

Our present invention relates to that class of derricks principally employed in logging in which the derrick is mounted upon a platform that may be either supported upon a flat car beneath it or by anindependent support permitting the flat cars to pass beneath it. Said independent support has sometimes consisted, as shown in our Patent No. 726325, substantially of legs supporting the derrick platform from the ends of the ties on opposite sides of the railway track or, as shown in the Baptist patent No. 662906, of a supplemental track section of greater gage than the railway track.

Our present invention is applicable to a derrick supported by either of these forms of independent support.

I11 our application No. 169862 filed August 18, 1903, we have shown the derrick platform when carried by the car beneath it as provided with an operative engagement between the engine on the platform and the wheel or wheels of the car, so that said engine can act as its own locomotive. In the use of the apparatus described in said application, whenever the derrick platform was set upon its independent supports for operation, it was necessary that the supporting or locomotive car should be run to a suflicient distance on the track to be out of the way of the other cars as they passed to, under and from the derrick in being loaded.

4 The object of our present invention is to provide means whereby said supporting or locomotive car when not in use for supporting or carrying the derrick can be disposed of adjacent to the derrick so as to be near at hand for use whenever required and in such manner as not to obstruct the track for the passage of other cars.

In the accompanying drawings, Figure 1 represents in plan view a car supplied with a traction mechanism and therefore adapted. to perform the function of the supporting oar described in our said application No. 169862. Fig. 2 shows in side view said car in position for supporting the derrick platform with its traction mechanism in operative connection with the derrick mechanism. Fig. 3 represents 1 said derrick as set upon its independent supports, and said car in full lines as adjacent thereto on the track. In dotted lines it represents said car as disposed in the manner in which we prefer according to our invention. Fig. 4 is a detail. Figs. 5 and 6 are front views partly in section to show the operation of the supports for the platform upon the car, in two positions.

1 is the railway track. 2 are the ties thereof.

3 is the derrick platform. 4, the derrickboom projecting from one end thereof. 5 is the rope-drum operating the hoisting-rope 6. 7 is a rope-drum operating the spotting-rope 8 whereby the cars are drawn as required under the platform or into loading position. 9 is a gear, 10 is the boiler mounted on said platform wherefrom all of said parts are driven by a suitable engine and connections mounted on said platform. 11 are the sup ports whereby said platform is supported independently of said cars on opposite sides of the track and at such an elevation above the track as to permit of the free passage of the cars underneath.

12 are supports between the derrick platform and the car platform onto which the support of the derrick platform may be transferred from the supports 11. A mechanism whereby these supports 12 may be operated is shown in detail in Figs. 5 and 6, wherein each pair of said supports 12 is coupled to a pair of levers 13 operated by a piston-rod 14 from a steam or hydraulic cylinder 15 so that the supports 12 may be forced downward until the mechanism on the derrick platform raises itself and the platform upon the car in the position shown in Figs. 2 and 6.

16 is the car-frame. 17 are the axles thereof to each of which is liked a sprocketwheel 18 connected, respectively, by the sprocket chains 19 with the sprockets 20 fixed to the shaft 21 to which is also fixed the spur-wheel 22 adapted to engage with the spur-wheel 9 already referred to. The shaft 21' has its bearings in a rocker-frame 23 fulcrumed on one of the car axles and counterbalanced by an adjustable weight 24.

- position.

25 is a latch secured to the car-frame whereby the rocker-frame 23 may be held in the position shown in Fig. 2 for engagement between the spur-wheels 9 and 22. By the release of said latch the rocker-frame falls into the position shown in Fig. 3 so that the presence of the traction mechanism on the car does not interfere with its use for any purpose that may be required or with the running of it to any point that may be desired. 26 are cross-beams secured to the top of the car-frame. 27 are eyes projecting above the said car beams.

To the rear of the derrick platform is pivoted a frame 28 consisting of two parallel booms secured together and capable of being moved from the. horizontal position shown in full lines, Fig. 3, to the vertical position shown in dotted lines by the boom-hoistingrope 29 which passes over the elevated sheave 30 around the sheave 31 and is coiled upon the winch-head 32, shown in Figs. 3 and 6. Projecting from the under side of the boom-frame 28 are hooks 33 so positioned that when the boom-frame is lowered each of them will enter one of the eyes 27 as the car is moved out from under the derrick platform. Each of these hooks is guarded by a latch 34 serving to retain the eyes within the hooks when the boom-frame 28 is hoisted in vertical The boom-hoisting-rope 29 may be passed around the sheave 35 and made fast to the car-frame at 36 so as to be adapted for hauling the car into a position beneath the boom from under the platform, thence to be hoisted up with the boom into the position shown in dotted lines by the further inhaul of the rope 29. When in the latter position, the boom is held as long as required by a latch 37.

It will be observed that under our present improvement, the supporting or traction-car instead of being disposed of-at a distance on the track way, as in our application No. 169862, is disposed of by being lifted bodily from the track. l/Ve do not wish to be understood as limiting ourselves to the manner in which this is accomplished al though we prefer to accomplish it in the manner above described because we thereby lift the car in .such position as to substantially register with the track upon being lowered and, also, in such position that it acts as a counterbalance to the weights being handled by the boom 4 of the derrick.

Although in the above description the car that is described as being raised bodily from the track is the supporting or traction car we, nevertheless, do not wish to limit ourselves in that regard because the same principle may be employed to temporarily get rid of a car where the neXt car behind it is the one required for the load.

In our co-pending application No. 181 ,714,

.we have shown lifting mechanism interposed between the derrick frame and the car, whereby said derrick frame may be mounted upon the car. The mechanism employed in said co-pending application is similar to that herein shown and in such case certain claims have been made to this form.
